This Kickstarter looks to jumpstart development of Defense Grid 2, a sequel to Hidden Path Entertainment's tower defense game. This one has an interesting approach, as there are funding goals to hit along the way. So if they raise $250K, they will create an eight-level expansion for the original Defense Grid; if they raise $500K they will build a new engine for a Defense Grid 2 remake with co-op multiplayer; at $750K they will add a level editor and other platforms; and if the campaign hits the $1M mark, they will be able to create the full sequel of their dreams. Thanks Bob.

short answer about the funding, most of the DG1 money went to paying back the original funding they got for it (they don't say if it was a loan, or publisher, or some investors who had to be paid back)
